** Description changed: + SRU Justification: + + Impact: Since "xen: Use IRQF_FORCE_RESUME" was accepted into upstream + stable for 2.6.32, a save/restore cycle will leave the guest in a halt + state after restore. + + Fix: Two upstream patches (one of those would be in the latest stable, the other had to be reverted as it broke compile on some architectures. The suggested patch is the revised version. + * xen/timer: Missing IRQF_NO_SUSPEND in timer code broke suspend. + * genirq: Add IRQF_RESUME_EARLY and resume such IRQs earlier + + Testcase: + * Boot pv-guest + * Run xm save <id> <file> on the dom0 + * Run xm restore <file> on the dom0 + * Try to re-connect to the console with xm console <id> + + --- + Description: Ubuntu 10.04.3 LTS Release: 10.04 When I'm restoring virtual machine after been saved (for example during shutdown) it completely freezes or sometimes is working, but I cannot execute interactive commands. This problem is related to linux-image-2.6.32-34-server package, because when I'm using 2.6.32-34 kernel, all is OK.
